Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Further, the term "and/or" in the present application is only one kind of association relationship describing the associated object, and means that three kinds of relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.
An SDN network system is provided in an embodiment of the present application, and as shown in fig. 1, includes a first network element device, a second network element device, and a controller. The first network element equipment and the second network element equipment establish network connection, and the controller respectively establishes network connection with the first network element equipment and the second network element equipment. The first network element device and the second network element device may directly establish network connection, or may establish network connection through other network element devices. The first network element device may be the network element device 1, the second network element device may be the network element device 2, or vice versa.
The controller is configured to issue a network quality measurement command for starting a specified object to a network element device in the network system, for example, to issue a network quality measurement command for starting measurement from a first network element device to a second network element device to the first network element device and the second network element device, and to issue measurement parameters to the first network element device and the second network element device, respectively. The measurement parameters include a measurement period, a transmission number of measurement messages, and a default value of a transmission interval. The default values of the measurement period and the measurement message transmission interval are set to be relatively small, and the default value of the measurement message transmission number is set to be relatively large, so that the quality condition of the measured network can be relatively accurately and quickly obtained. For example, the controller issues measurement parameters with a measurement cycle of 5s, a transmission number of measurement messages of 5, and a transmission interval of measurement messages of 1s to the network element device.
The measurement parameters issued by the controller to the first network element device and the second network element device may be the same.
The first network element equipment is used for sending a measurement message to the second network element equipment according to the measurement parameter, and the second network element equipment is used for measuring the network quality of the received measurement message according to the measurement parameter to obtain network quality measurement data and reporting the network quality measurement data to the controller. The second network element device summarizes the measurement data obtained from each measurement packet in the measurement period to obtain network quality measurement data, and reports the network quality measurement data to the controller. The specific process of the network element device performing network quality measurement on the network under test is well known in the art and will not be described here.
The controller is further configured to analyze the quality condition of the measured network based on the received network quality measurement data to obtain an analysis result, adjust the measurement parameter according to the analysis result, and send the adjusted measurement parameter to the first network element device and the second network element device.
In order to make the analysis result more accurate, when analyzing the quality condition of the measured network based on the received network quality measurement data, the controller analyzes the quality condition of the measured network based on the received network quality measurement data of a plurality of cycles, for example, analyzes the quality condition of the measured network based on the received network quality measurement data including the current cycle and N cycles preset before the current cycle, where N is a positive integer, such as 1, 2, 3 … …, and the like. For example, the quality condition of the measured network is analyzed based on the received network quality measurement data of 3 periods including the current period.
Wherein, the controller analyzes the cycle times value of the network quality measurement data, and can be set according to the condition: the smaller the value, the faster the perception of the change in network quality; the larger the value is, the more accurate the regular analysis of the traffic flow characteristics is.
The quality condition analysis of the network may be analysis of at least one of link delay, link jitter, packet loss and other indicators. For example, the network quality measurement data includes link delay data corresponding to each measurement packet in a measurement period, and when analyzing the link delay condition of the measured network, whether the link delay data corresponding to each measurement packet in each measurement period are stable or not and whether the fluctuation amplitude between the link delay data of N periods preset before the current period and the current period is stable or not may be analyzed, so as to obtain an analysis result. The link jitter can be obtained from the average value of the link delay data of each period. The packet loss can be obtained according to the number of the transmitted measurement messages and the number of the received measurement messages. The specific analysis process of the network quality situation is well known to those skilled in the art and will not be described here.
If the analysis result represents that the network quality is stable, the measurement period can be increased and/or the transmission frequency of the measurement message can be reduced when the measurement parameters are adjusted; if the analysis result indicates that the network quality is unstable, the measurement period can be reduced and/or the transmission frequency of the measurement message can be increased when the measurement parameter is adjusted.
In order to avoid the measurement parameter being too large or too small, an upper limit value and/or a lower limit value of the measurement parameter may be set in advance, before the measurement parameter of the network element device is adjusted according to the analysis result, it may be determined whether the current measurement parameter of the network element device reaches a preset limit value (upper limit value or lower limit value), and when it is determined that the current measurement parameter of the network element device does not reach the preset limit value, the measurement parameter of the network element device is adjusted. And if the measurement parameter of the current network element equipment reaches the preset limit value, the measurement parameter is not adjusted. In order to ensure the effectiveness and accuracy of the network quality measurement data, each measurement parameter may be set to an upper limit value or a lower limit value according to the situation.
In order to avoid that the change of the network quality cannot be sensed timely under the long-time low-sensitivity measurement condition, the controller is further configured to determine whether the cumulative number of times of measurement parameters of the continuous unadjusted network element device reaches a preset threshold, where M is a positive integer greater than 1, and if M is a preset threshold; and if the cumulative times of the measurement parameters of the continuous unadjusted element equipment reach a preset threshold value, issuing the initial measurement parameters to the element equipment so that the element equipment can measure the network quality of the measured network based on the initial measurement parameters. The value M may be set according to circumstances.
For ease of understanding, the following description is made with reference to examples:
the controller issues a network quality measurement command for starting the measurement network element device 1 to the network element device 2 to the network element device 1 and the network element device 2, and issues measurement parameters with a measurement cycle of 5s, a measurement message sending number of 5, and a measurement message sending interval of 1 s. The upper limit value of the measurement parameter of the controller is set as follows: the measurement period is 60s, the transmission number of the measurement messages is 6, and the transmission interval of the measurement messages is 10 s; the controller has an N value set to 2 and an M value set to 10.
The network element equipment 1 sends a measurement message to the network element equipment 2 according to the issued measurement parameters; the network element device 2 measures the link delay of the received measurement packet by using the prior art according to the issued measurement parameter, and summarizes and reports the link delay data obtained from each measurement packet in the measurement period to the controller. Assume that the 0 th to 15 th second link delay data are as shown in fig. 2. The 1 st, 2 nd and 3 rd periods of link delay data reported by the network element device 2 to the controller are respectively as follows:
cycle 1: 5.1ms, 5.1ms, 5.2ms, 5.2ms and 5.3 ms;
and 2, period: 5.3ms, 5.2ms, 5.2ms, 5.1ms and 5.0 ms;
cycle 3: 4.9ms, 4.8ms, 4.8ms, 4.9ms, 4.9 ms.
The controller analyzes the quality condition of the measured link, such as the link delay, based on the received link delay data of the 1 st, the 2 nd and the 3 rd periods to obtain an analysis result with a smaller delay jitter value and a more stable link state, and can further increase the measurement period and reduce the transmission frequency of the measurement message appropriately to save network resources; therefore, the controller adjusts the measurement parameters, the measurement period is adjusted to 10s, the transmission number of the measurement messages is still 5, and the transmission interval of the measurement messages is adjusted to 2 s. And then the adjusted measurement parameters are sent to the network element equipment 1 and the network element equipment 2.
During the analysis, whether the link delay data corresponding to each measurement packet in each measurement period is stable or not and whether the fluctuation amplitude between the link delay data of 3 periods is stable or not can be analyzed. For example, whether the link delay data corresponding to each measurement packet in each measurement period is stable may be analyzed according to whether a difference between a maximum value and a minimum value in the link delay data corresponding to each measurement packet in each measurement period is greater than a threshold, and if the difference between the maximum value and the minimum value is less than the threshold, the stability is achieved. Whether the fluctuation amplitude among the 3 periods of link delay data is stable or not can be analyzed according to the average value of the 3 periods of measurement, and if the change of the average value of the link delay data is not large, the fluctuation amplitude among the 3 periods of link delay data can be considered to be stable.
The network element equipment 1 adjusts the measurement period and the measurement message sending interval according to the measurement parameters sent by the controller, and sends the measurement messages to the network element equipment 2; the network element device 2 adjusts the measurement period and the measurement message transmission interval according to the measurement parameters issued by the controller, continues to use the prior art to measure the link delay of the received measurement message, and summarizes and reports the link delay data obtained from each measurement message in the measurement period to the controller. Assume that the 15 th to 25 th second link delay data are as shown in fig. 3. The 4 th cycle of link delay data reported by the network element device 2 to the controller is as follows:
and 4, period: 5.1ms, 5.2ms, 5.2ms, 5.1ms, 4.9 ms.
The controller analyzes the quality condition of the measured link, such as the link delay, based on the received link delay data of the 2 nd, the 3 rd and the 4 th periods: the analysis result that the delay jitter value is still small and the link state is continuously stable is obtained, so that the measurement period can be further properly increased and the transmission frequency of the measurement messages can be further reduced to save network resources, therefore, the controller adjusts the measurement parameters, adjusts the measurement period to 20s, the transmission number of the measurement messages to 5, the transmission interval of the measurement messages to 4s, and then sends the adjusted measurement parameters to the network element equipment 1 and the network element equipment 2.
The network element device 1, the network element device 2 and the controller continuously perform the above processes, and assuming that the delay condition of the measured link is continuously stable, the controller has adjusted the measurement parameter to the set upper limit value in a certain period, for example, the 7 th period: the measurement period is 60s, and the measurement message transmission interval is 10 s. And under the condition that the time delay condition of the measured link is continuously stable, the measurement parameter is kept unchanged in the subsequent period and is not adjusted any more.
Assuming that the delay condition of the measured link is deteriorated in the subsequent Y-th cycle, the link delay data of the Y-th cycle is as shown in fig. 4. The link delay data of the Y-th cycle reported by the network element device 2 to the controller is:
and a Y period: 6.3ms, 11.2ms, 16.4ms, 19.1ms, 18.6ms and 14.9 ms.
The controller analyzes the quality condition of the measured link, such as the time delay condition, based on the received Y-2, Y-1 and Y-cycle link time delay data: and obtaining an analysis result of the time delay jitter value with mutation, immediately reducing the measurement period and increasing the transmission frequency of the measurement message to quickly and accurately obtain the latest link time delay data, so that the controller adjusts the measurement parameters, adjusts the measurement period to 5s, adjusts the transmission number of the measurement messages to 5s, and adjusts the transmission interval of the measurement messages to 1 s. And then the adjusted measurement parameters are sent to the network element equipment 1 and the network element equipment 2. The subsequent processing refers to the above process.
If the delay condition of the measured link is continuously stable and the cumulative number of times of measurement parameters of the network element device 1 and the network element device 2 that are continuously not adjusted by the controller reaches a preset threshold, for example, 10 times (a set M value), the initial measurement parameters are issued to the network element device 1 and the network element device 2, that is, the measurement parameters with a measurement cycle of 5s, a measurement message sending number of 5, and a measurement message sending interval of 1s are issued to the network element device 1 and the network element device 2, so that the situation that the change of the delay condition of the measured link cannot be timely sensed under the 'low-sensitivity' measurement condition for a long time is avoided.
The network element device in the embodiment of the present application may be a router or a switch, and the controller is an SDN controller.
Based on the same inventive concept, the embodiment of the present application further provides a network quality monitoring method, and the network quality monitoring method provided by the embodiment of the present application will be described below with reference to fig. 5.
S1: and receiving network quality measurement data reported by the network element equipment.
The network element equipment measures the network quality of the network to be measured according to the initial measurement parameters, and reports the obtained network quality measurement data to the controller after summarizing the measurement data obtained by each measurement message in each period.
S2: and analyzing the quality condition of the measured network based on the received network quality measurement data to obtain an analysis result.
In order to make the analysis result more accurate, when analyzing the quality condition of the measured network based on the received network quality measurement data, the quality condition of the measured network is analyzed based on the received network quality measurement data including the current period and N periods before the current period, where N is a positive integer, such as 1, 2, 3 … …, etc.
The network quality measurement data comprises link delay data corresponding to each measurement message in a measurement period; when analyzing the quality condition of the measured network based on the received network quality measurement data including the current period and N periods preset before the current period, the method may be: whether the link time delay data corresponding to each measurement message in each measurement period are stable or not is analyzed, and whether the fluctuation amplitude between the link time delay data of the current period and the preset N periods before the current period is stable or not is analyzed.
S3: and adjusting the measurement parameters of the network element equipment according to the analysis result, and sending the adjusted measurement parameters to the network element equipment.
And after the analysis result is obtained, adjusting the measurement parameters of the network element equipment according to the analysis result, and sending the adjusted measurement parameters to the network element equipment so that the network element equipment can measure the network quality of the measured network based on the adjusted measurement parameters.
The measurement parameters comprise a measurement period and a measurement message sending frequency; the process of adjusting the measurement parameters of the network element device according to the analysis result may be: if the analysis result represents that the network quality is stable, increasing the measurement period and/or reducing the transmission frequency of the measurement message; if the analysis result represents that the network quality is unstable, the measurement period is reduced and/or the transmission frequency of the measurement message is increased.
In order to avoid the measurement parameter being too large or too small, an upper limit value and/or a lower limit value of the measurement parameter may be set in advance, and before the measurement parameter of the network element device is adjusted according to the analysis result, the method further includes determining that the measurement parameter of the current network element device does not reach the preset limit value. In this embodiment, it is necessary to first determine whether the measurement parameter of the current network element device reaches a preset limit (an upper limit or a lower limit), and only when it is determined that the measurement parameter of the current network element device does not reach the preset limit, the measurement parameter of the network element device is adjusted. And if the measurement parameter of the current network element equipment reaches the preset limit value, the measurement parameter is not adjusted. In order to ensure the effectiveness and accuracy of the network quality measurement data, each measurement parameter may be set to an upper limit value or a lower limit value according to the situation.
In addition, if the measurement parameter of the current network element device reaches the preset limit value, whether the cumulative number of the measurement parameters of the continuous unadjusted network element device reaches the preset threshold value or not can be further judged, and if the cumulative number of the measurement parameters of the continuous unadjusted network element device reaches the preset threshold value, the initial measurement parameter is issued to the network element device, so that the network element device can measure the network quality of the measured network based on the initial measurement parameter, and the situation that the change of the network quality cannot be timely sensed under the 'low-sensitivity' measurement condition for a long time is avoided.
